N-Descyclopropanecarbaldehyde Olaparib, an Olaparib analogue, incorporates a DOTA moiety. It acts as a CRBN-based ligand for the formation of novel dual EGFR and PARP PROTAC, DP-C-4[1]. N-Descyclopropanecarbaldehyde Olaparib is suitable for radiolabeling with F-18 or a fluorophore to visualize tumors using positron emission tomography (PET) or optical imaging[2].
PARP1-IN-9 (Compound 5c) is a potent PARP1 inhibitor, displaying an IC 50 of 30.51 nM. With its ability to induce cell apoptosis and exhibit anticancer activity, PARP1-IN-9 surpasses Olaparib in terms of efficacy [1].
